SEAL FOR PHONOGRAPI- IIC RECORDS.

SPECIFICATION forming part of Letters Patent N 0. 692,624, dated February 4, 1902. Application filed April 22, 1901. Serial No. 56,829. (No modelJ To all whom, it may concern:

Be it known that I, ALFRED CLARK, a citizen of the United $tates, residing at Paris, France, have invented certain new and useful Improvements in Seals for Phonographic Records, of which the following is a specification.

The object of this invention is to provide a seal upon a phonographic record in order that such records may be placed on sale and protected against use, so .as to prevent them from being injured.

Each time that a phonographic record is used to reproduce the sounds recorded on it the irregularities in the record-groove corresponding to the sound-waves are partially destroyed and the record is to that extent injured. To prevent this, I provide a seal which may be attached to the record, the object being so to apply such seal to the phonographic record that it must be broken or deplacing the record upon the phonograph.

My invention as illustrated is applied to cylinders and to disks, and when so applied the seal may be so attached thereto by means of a tape or other suitable fabric passing through the bore of the cylinder or through the central or other aperture of the disk and having its ends joined by means of wax or its equivalent.

In the drawings which accompany this specification, Figures 1, 2, and 3 show my invention applied thereto. Fig. 1 represents a cylinder having a tape passing through the central opening and having the ends joined and secured by wax or its equivalent. Figs.

2 and 3 represent a disk having a tape or similar material passing through the central aperture and having the ends joined and secured by wax or its equivalent.

Like letters of reference indicate similar parts throughout the drawings.

or represents a cylindrical phonographic record having the tape or other suitable fabric 1) passed through its bore 01 and having its ends sealed at c.

e represents a flat disk of a material suit able for a phonograph or other talking-Ina chine record.

1) indicates a tape or other suitable fabric passed through the central aperture f.

I use the word phonographic in a broad sense as applying to all kinds of machines for recording and reproducing sounds.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

A phonographic record having a seal= shackle passed through its central bore or aperture andhaving its ends united and sealed by wax or its equivalent, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 9th day of April, 1901.

ALFRED CLARK.
